The smart set’s talking about... Camilla’s pop star daughter-in-law

QUEEN Camilla could soon have a pop princess in the family.

I hear that her daughter-in-law, Sara Parker Bowles, has co-written a song she hopes is destined for the charts.

Fashion writer Sara, 49, who’s estranged from Camilla’s son Tom, composed the tune while on a retreat for aspiring songwriters in Spain.

‘It’s called What If and is my new single,’ her co-writer, Simon Coulson, tells me.

The millionaire businessman explains: ‘ We’d never met before, but one of the activities is to write a song together, then play it to the rest of the group.

‘Sara helped pen the track and even sang backing vocals.’

Next stop, a performance at Buckingham Palace?
